Muscle disorders can cause weakness, pain, or even paralysis. They can be caused by genetic conditions, autoimmune diseases, or other unknown factors. Some muscle diseases are secondary to other more serious health conditions. Neuromuscular disorders, a type of muscle disorder, affect the nerves that control voluntary muscles and the nerves that communicate sensory information to the brain. Muscular dystrophy, a group of inherited diseases, is another type of muscle disorder that causes progressive weakness and loss of muscle mass.

Muscular dystrophy
There are many types of muscular dystrophy, including:
- Myotonic dystrophy: This is the most common type diagnosed in adulthood and affects men and women equally. People with myotonic dystrophy have difficulty relaxing their muscles after using them.
- Congenital muscular dystrophies (CMD): CMD refers to a group of muscular dystrophies apparent at or near birth, causing overall muscle weakness and possible joint stiffness or looseness.
- Becker muscular dystrophy (BMD): BMD is the second most common type and mainly affects boys, but girls can have milder symptoms. Symptoms typically appear between ages 5 and 60, starting in the teenage years.
- Emery-Dreifuss muscular dystrophy (EDMD): EDMD primarily affects male children and young adults, causing muscle weakness in the shoulders, upper arms, and shins. It also affects the heart and usually progresses slowly.
- Facioscapulohumeral muscular dystrophy (FSHD): FSHD commonly affects muscles in the face, shoulders, and upper arms. It affects about 4 out of 100,000 people in the US and usually appears before age 20.
- Limb-girdle muscular dystrophy (LGMD): LGMD affects the muscles in the upper arms, upper legs, shoulders, and hips. It affects people of all ages, with approximately 2 out of 100,000 people affected in the US.
While there is currently no cure for muscular dystrophy, medications and therapy can help manage symptoms and slow the disease's progression. Treatment by an experienced multidisciplinary team is vital to enhancing the quality of life for patients.

Neuromuscular disorders
Muscle disorders can cause weakness, pain, or even paralysis. They can also affect important bodily structures, leading to muscle wasting and disability. Neuromuscular disorders are a type of muscle disorder that affects the nerves that control voluntary muscles and the nerves that communicate sensory information to the brain. When nerve cells (neurons) become unhealthy or die, the communication between the nervous system and muscles breaks down, resulting in muscle weakness and atrophy.
There are many types of neuromuscular disorders, and they can be caused by a variety of factors. Some neuromuscular disorders are genetic and may be inherited or caused by a new mutation in the affected individual. For example, muscular dystrophy, a common neuromuscular disorder, is caused by abnormal genes (mutations) that interfere with the production of proteins needed for healthy muscle development. Other neuromuscular disorders may be autoimmune diseases, where the immune system attacks its own healthy muscle tissues. In some cases, the cause of neuromuscular disorders is unknown.
The symptoms of neuromuscular disorders depend on the specific type and the areas of the body affected. Some people may experience progressive muscle weakness, trouble walking or using their arms, and difficulty with daily activities. Other symptoms can include muscle inflammation, chronic dry cough, difficulty swallowing, breathing problems, and heart issues. Some neuromuscular disorders have symptoms that begin in infancy or childhood, while others may appear in adulthood.
Currently, there is no cure for neuromuscular disorders, but treatments are available to manage symptoms and improve quality of life. These treatments include medications, physical therapy, occupational therapy, and, in some cases, surgery. Research is ongoing, and there is hope that genetic therapies and new medications may lead to a cure in the future.
It is important to seek medical advice if you or your child experience signs of muscle weakness, such as increased clumsiness or falling. Doctors can evaluate symptoms and order diagnostic tests to determine the underlying cause and rule out other potential disorders. Thorough clinical and neurological exams are often conducted, and genetic testing and counseling may also be recommended.

Muscle inflammation
There are two specific types of myositis: polymyositis and dermatomyositis. Polymyositis causes muscle weakness, usually in the muscles closest to the trunk of the body. Dermatomyositis causes muscle weakness and a skin rash, which can be red or purple and itchy, and may appear on the scalp, around the eyes, chest, and hands.
In some cases, myositis can affect breathing and swallowing, and occasionally it may cause weakening of the heart. Lung and heart conditions associated with myositis can lead to long-term breathlessness. Myositis can also cause inflammatory arthritis, which results in pain and swelling of the joints, as well as interstitial lung disease, characterised by a cough and/or shortness of breath.
The muscle inflammation in myositis is caused by white blood cells of the immune system, which mistakenly injure muscles and other tissues. While anyone can get myositis, people in their middle age, women, and those with Sub-Saharan African descent are at higher risk. The exact cause of myositis is unknown, but it is estimated that about 50,000 people in the US are living with the disease.
Another condition that can result in muscle inflammation is muscular dystrophy, a group of diseases that cause progressive weakness and loss of muscle mass. This condition interferes with the production of proteins needed to form healthy muscles. Muscular dystrophy can lead to trouble walking, using arms, breathing, swallowing, and heart problems.

Muscular Dystrophy
Muscular dystrophy (MD) is a group of inherited genetic diseases that cause progressive weakness and degeneration of skeletal muscles. There are more than 30 forms of MD, and they vary in age of onset, severity, and the pattern of affected muscles. All forms of MD grow worse over time as muscles progressively degenerate and weaken. The most common form of MD is Duchenne muscular dystrophy, which primarily affects boys, although girls who carry the defective gene may show some symptoms. The next most common is Becker muscular dystrophy. Other types include myotonic, facioscapulohumeral (FSHD), congenital, and limb-girdle muscular dystrophy. Symptoms of muscular dystrophy can include trouble walking, difficulty using arms, shortening of muscles or tendons around joints (contractures), breathing problems, a curved spine (scoliosis), heart problems, and swallowing difficulties. There is currently no cure for muscular dystrophy, but medications and therapy can help manage symptoms and slow the course of the disease.
Neuromuscular Disorders
Neuromuscular disorders affect the nerves that control voluntary muscles and the nerves that communicate sensory information back to the brain. When the nerve cells (neurons) become unhealthy or die, communication between the nervous system and muscles breaks down, resulting in muscle weakness and atrophy. There are many types of neuromuscular disorders, and they can result in muscle weakness and fatigue that progress over time. Symptoms depend on the specific disorder and the areas of the body that are affected. There is currently no cure for neuromuscular disorders, but they can be treated with medications, physical therapy, occupational therapy, and, when necessary, surgery.
Other Conditions
Other conditions that can cause muscle weakness include myostatin-related muscle hypertrophy, myotonia congenita, nemaline myopathy, neutral lipid storage disease with myopathy, paramyotonia congenita, phosphoglycerate kinase deficiency, phosphoglycerate mutase deficiency, potassium-aggravated myotonia, rippling muscle disease, STAC3 disorder, and tubular aggregate myopathy. Additionally, some muscle diseases are autoimmune, where the immune system attacks its own healthy muscle tissues. In some cases, the cause of muscle weakness may be unknown.

Muscle wasting
Muscular dystrophy is a group of inherited genetic diseases that cause progressive weakness and degeneration of skeletal muscles. There are more than 30 types of muscular dystrophy, and symptoms can begin in childhood or adulthood, depending on the type. The most common form, Duchenne muscular dystrophy, primarily affects boys due to a mutation on the X chromosome. Other types include Becker muscular dystrophy, facioscapulohumeral muscular dystrophy, and limb-girdle muscular dystrophy. Symptoms of muscular dystrophy include trouble walking, difficulty using arms, contractures, breathing problems, scoliosis, heart problems, and swallowing disorders. While there is no cure for muscular dystrophy, medications and therapy can help manage symptoms and slow the progression of the disease.
